CVE-2021-27438
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe software contains a hard-coded password it uses for its own inbound authentication or for outbound communication to external components on the Reason DR60 (all firmware versions prior to 02A04.1).
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Reason DR60 device (all firmware versions prior to 02A0.1) contains a hard-coded password embedded in the firmware that is used for the device's own inbound authentication or for outbound communication to external components. An attacker with knowledge of this hardcoded credential could authenticate to the device or intercept communications.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify DR60 firmware versionAccess the device management interface or check the firmware file loaded on the device. Navigate to System Status or About section in the DR60 web interface or console to retrieve the current firmware version number.Affected if The displayed firmware version is earlier than 02a04.1 (for example, 02a00, 01x, or any version number that numerically precedes 02a04.1).
-
Locate device credentials configurationInspect the DR60 device configuration files or firmware image for embedded password strings. This may be accessible through the device's backup configuration export, via TFTP/FTP download of the firmware, or by examining firmware binaries if you have local access.Affected if A hardcoded password string is found embedded in the firmware binary, configuration file, or device backup that was not set by the administrator.
-
Test default authenticationAttempt to authenticate to the DR60 device using known default credentials or the documented hardcoded credential associated with this vulnerability. Use the device's login portal or API endpoint.Affected if Authentication succeeds using a credential that was not explicitly configured by your organization or that matches known hardcoded values for this device model.
Your environment is affected if the DR60 device runs firmware version prior to 02a04.1 and contains the hardcoded password referenced in this CVE.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data02a04.1
Update the DR60 firmware to version 02A0.1 or later to remove the hardcoded password, and change any default credentials used by the device.
